Enhancing Cyber Resilience in Smart Buildings

Building Automation Systems (BASs) are essential components of smart buildings, functioning as the core intelligence that enables efficient and intelligent operations. To support capabilities such as remote monitoring, cloud-based analytics, and integration with smart grids, BASs increasingly rely on connectivity—both within the building and with external networks like the Internet and cloud platforms. The shift toward open communication protocols has made remote access to BASs more common, improving convenience and operational efficiency. However, this rise in connectivity also increases exposure to cybersecurity risks. Many BASs were originally designed as closed, isolated systems with minimal attention to cyber threats. As a result, these systems are now vulnerable to various attacks that could disrupt building operations, cause occupant discomfort, increase energy waste, or lead to equipment failure. The growing reliance on interconnected digital infrastructure in buildings makes it critical to address these security challenges. To ensure safe and resilient building environments, it is necessary to enhance cyber-physical security frameworks for BASs and implement effective strategies to detect, prevent, and respond to cyber threats.
